In 2009 an additional £100,000 will be spent on exploration. If total annual expenditure increases
by 8%, what proportion of overall expenditure will exploration account for?
 

 

Correct answer: B

Explanation
If total expenditure increased by 8%, the new total expenditure = 1.08 x 4,000,000
= 4,320,000
Percentage spent on exploration in 2008 = 29%
Proportion spent on eploration = (0.29 x 4320000) + 100000/4320000
= 0.3131 = 31.31%

What was the percentage decrease in the cost of mining from 2007 to 2008?
 

 

Correct answer: C

Explanation
Cost of mining in 2007 = 0.19 x 3,400,000
= 646,000
Cost of mining in 2008 = 0.12 x 4,000,000 = 480,000
% decrease = (646,000 - 480,000)/646,000
= 25.7%

What was the percentage increase in the cost of exploration from 2007 to 2008?
 

 

Correct answer: A

Explanation
Cost of exploration in 2007 = 0.2 x 3,400,000
= 680,000
Cost of exploration in 2008 = 0.29 x 4m
= 1,160,000
% increase = (1,160,000 - 680,000)/680,000 x 100
= 71%

What was the total expenditure of mining and logistics in 2007?

Mining = 19% of 3,400,000 = 646,000
Logistics = 18% of 3,400,000 = 612,000
646,000 + 612,000
= 1,258,00

If 90% of cars in Argentina are owned by urban dwellers, what percentage of urban dwellers
own cars (assuming a maximum of one car per person)?

 

Correct answer: D

Explanation
Total number of vehicle cars = 1.1m
Urban dwellers own (90/100) x 4.1m = 3.69m cars Ratio of urban to rural = 86.4 : 13.6
Total pop = 35.6
Urban dwellers = (86.4/100) x 35.6 = 30.76m
% of urban dwellers with cars = (3.6m/30.76m) x 100
= 12%
